If anyone here has the answer to this they can PM me.
My wife and I were married as Methodists. 5 years later after, just after the birth of our 3rd child the JW Cultists started a bible study with her while I worked to support a fine young family. This study was kept secret from me for 8 months until I just happend upon it one day as I had to go past the house on the way to a service call and noticed a strange car there. Looking back now after 31+ years of marriage it was though she was having an affair with another guy. It is the same thing. Her affair was with the WTBS Org and the elders of her congretation dictating how she should interact with her unbelieving spouse. It made me feel like crap to have a wonderful, beautiful wife who would only put on a dress and display herself for the wittness clan. Some will advise you to play the "headship" card but I can tell you that if there was such a card they wouldn't have kept the bible study a secret. I you do try to play that fictious card it wil only be trumped by the "obey god before man" card.
I wish you the best my heart can offer in the struggle you confront. Do keep loving her whatever the outcome because that is the final defeat of satan.
I am divorced now and she is remarried to a guy she drew into the wittnesses. I know that was her greatest desire with me. To draw me in. They preached it to her over and over that one day she might "save" me. When it didn't happen she grew more and more frustrated with our relationship. After our children were grown and gone she just devoted more and more of herself into the WTBS. Over the years I had tried everything, go to some meetings, go to all the meetings, to to assemblies and conventions; go to some, all or none. In my heart, nothing short of being a babtised wittness would be sufficient. In my heart I could not do that and be a fake.
I sincerely hope she is happy today being a submissive wittness wife. I still love her with all my heart. It just so happens they are my next door neighbors. I do live with the satisfaction of knowing he is living in the house I bought and paid for; she cooks in a wonderful kitchen that I completely remodeled; they sit and eat at polished table built by my hands; sit on a couch I bought and paid for; and on and on.
Keep the love you have and God wins. I rarely quote scriptures but I can tell you there is one in Matthew about how in the paradise to come there won't be husbands and wives. I believe in that paradise but I don't think it will be like the one that the WTBS portrays in their fine art.
You probably feel differently but to me the WTBS is a destroyer. Most of the people are sincere and compassionate the head is part of satan.
